A TTOHNE rs UNITED STATES PATENT OFFICE.

FERDINAND BLAUSS, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO GEORGE J. SOI-INATZ, on SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No.420,6'73, dated February 4, 1890. Application filed December 9, 1889. Serial No. 333,023. (No model.)

To all whom it may concern Be it known that I, FERDINAND BLAUSS, of the city, county, and State of New York, have invented a new and Improved Automatic Car-Coupler, of which the following is a full, clear, and exact description.

The object of my invention is to provide a car-coupler of the li'nk-and-pin type, which shall be automatic in coupling without materially changing the common form of drawhead now used in this class of couplers.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate J corresponding parts in all the figures.

Figure 1 is a sectional plan view of my new automatic car-coupler. Fig. 2 is a sectional elevation of the same. Fig; 3 is a front elevation of one of the draw-heads and its pin, and Fig. 1 is an enlarged perspective View of the connecting-link.

The invention will first be described in connection with the drawings, and then pointed out in the claims. 7

A A represent the draw-heads 'held by the cross-plates B B, or by any other suitable means, to and between the draw-head timbers O O. The draw-heads may be of usual form with the curved side pieces a a at the mouth, and with the aperture a in the top wall and the" corresponding hole or aperture a in the bottom wall.

D D are the coupling-pins fitted in aper tures a a to retain the coupling-link E.

Each coupling-pin D is formed at the lower end with a small round projection or point (Z, to lit in the bottom aperture a 7 Within the draw-head the pin is formed with a cam d, with an inclined face d against Which formed the point of the connecting-link strikes to automatically lift the pin. The connectinglink E is formed at its ends with the inclined faces or cams e, to facilitate the lifting of the coupling-pins: Between these inclined faces the link is recessed at e", to form clearances for the project-ions d at the lower ends of the coupling-pins, the cams d and inclines e serving to lift coupling-pins sufficiently to permit the bridgepieces 6 to pass under the projections d of the coupling-pins. After said bridge-pieces pass the projections d, the enlarged spaces E in the connecting-link permit the couplingpins to drop behind the bridge-pieces 6, so the cam d rests upon the bottom of the drawhead and the projection d in the aperture a thus effectually coupling the cars.

The coupling-pins may be prevented from lateral displacement by the yoke-pieces F, secured to the upper surfaces of the drawheads, if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The draw-head formed with top and bottom apertures and the coupling pin constructed to fit said apertures and formed with a cam in the draw-head, combined with a connecting-link formed with camfaces, a

bridge between the same and an enlarged space or opening back of the bridge, substantially as described.

2. The connecting-link E, formed with en larged spaces E, recesses e at the ends, and bridge-pieces 8 substantially as described.

3. The connecting-link formed with enlarged spaces E, inclined faces e, end recesses e, and bridge-pieces 6 in combination with the draw-heads provided with coupling-pins formed with cams d within the cavity of the draw-heads, substantially as described.

. FERDINAND BLAUSS.
